Quick compiler: support for 006, 012, 013, 017

Continued fleshing out of the Quick compiler.  With this CL,
we're passing run-tests 006, 012, 013 and 017.  Note minor
changes to the tests to allow for easy identification of methods
we want to run through the Quick path.  Also, set up by default
now to dump bitcode file to /sdcard/Bitcode/
